According to China Chemical Industry News, a recent article in Chemical & Materials analyzed the ammonium sulfate market. The report indicates that the global market size stood at $4.5 billion in 2025 and is projected to grow to $5.7 billion by 2035—an increase of $1.2 billion (or 26.7%) over the decade—reflecting a compound annual growth rate (CAGR) of 2.4%. Driven by rising global food demand, the need to boost agricultural productivity, and the increasing adoption of dual-action nitrogen-sulfur fertilizers across crop cultivation, industrial processing, and fine chemical sectors, the market volume is expected to expand to 1.27 times its initial size over this ten-year period.

**Continued Global Market Expansion**

The report notes that between 2025 and 2030, the ammonium sulfate market will grow from $4.5 billion to $5.0 billion—an increase of $500 million, accounting for 41.7% of the total ten-year growth. Industry development during this phase will be driven by heightened focus on food security, the advancement of intensive agriculture, and rising demand for sulfur-containing fertilizers. Growers and chemical companies worldwide are expanding ammonium sulfate production capacity to meet the essential market demand for high-efficiency nitrogen-sulfur fertilizers and to enhance crop yields and soil quality.

From 2030 to 2035, the market size is projected to rise from $5.0 billion to $5.7 billion, adding $700 million in value and accounting for 58.3% of the total ten-year growth. During this period, demand for specialized fertilizers—supporting sustainable agriculture, precision fertilization technologies, soil improvement, and crop quality enhancement—will serve as the primary growth engine. The widespread adoption of integrated nutrient management and sustainable cultivation practices will further drive market demand for efficient, environmentally friendly ammonium sulfate.

The report also analyzes ammonium sulfate market segments. Regarding product form, granular ammonium sulfate remains the dominant choice compared to crystalline and liquid forms; the report indicates that granular ammonium sulfate accounted for 52% of the market in 2025. With its excellent flowability, suitability for mechanized spreading, resistance to caking during storage, and uniform field application, granular ammonium sulfate is compatible with various types of agricultural machinery and large-scale farming operations, making it the preferred formulation for the agricultural sector. As precision fertilization equipment becomes more widespread, the advantages of granular ammonium sulfate will be further amplified, establishing it as a mainstay in agricultural input distribution and field crop fertilization.

In terms of application, agricultural use dominates the market. The report indicates that in 2025, the agricultural sector will account for 72% of total ammonium sulfate demand, serving as the core pillar of industry growth. The remaining demand is distributed across industrial, feed, and other niche sectors.

Regarding production pathways, ammonium sulfate is currently primarily sourced through two methods: recovery as a by-product of caprolactam production and direct chemical synthesis.

Three major market trends

Factors such as population growth necessitating increased grain production, the acceleration of agricultural intensification, the adoption of balanced fertilization practices, and steadily rising demand for nitrogen-sulfur dual-nutrient fertilizers are driving the growth of the ammonium sulfate market. However, the industry also faces constraints, including competition from straight nitrogen fertilizers like urea, environmental regulatory pressures regarding ammonia emissions and soil acidification, and bottlenecks in upstream raw material supply and production capacity.

The report outlines three key trends shaping the future of the ammonium sulfate market: First, the spread of eco-friendly farming practices will boost demand for ammonium sulfate products with a low environmental footprint, making high-efficiency, specialized products a focus of R&D. Second, the widespread adoption of modern agricultural technologies—such as GPS-based variable-rate fertilization and real-time soil monitoring—will drive the development of customized ammonium sulfate blended fertilizers. Third, the rise of high-value cash crops (such as fruits, vegetables, and traditional medicinal herbs) is spurring the emergence of new products, including slow- and controlled-release, inhibitor-enhanced, and specially coated ammonium sulfate; companies can capitalize on this by intensifying R&D in coating and additive technologies, focusing on the cash crop sector, and targeting high-end, differentiated markets.

Market participants include large fertilizer conglomerates, fine chemical enterprises, and integrated agricultural service providers. The report suggests that companies can build competitiveness through cost-reducing technical upgrades, new product R&D, green manufacturing, and niche, customized products, with granulation, coating, and efficiency-enhancing formulations serving as the core directions for product evolution.

Divergent trends across key national markets

The report analyzes the projected compound annual growth rates (CAGR) for the ammonium sulfate market in key countries from 2025 to 2035. Specifically, the figures are 2.8% for the United States, 2.6% for Mexico, 2.2% for Germany, 2.1% for France, 1.9% for the UK, 1.8% for South Korea, and 1.7% for Japan.

United States: Large-scale cultivation and precision agriculture drive global growth. Supported by a system of large farms, precision agricultural technologies, and comprehensive technical services, major US grain-producing regions (such as the Corn Belt, wheat zones, and specialty fruit and vegetable areas) exhibit strong demand for balanced fertilization. Domestic agribusinesses have optimized their ammonium sulfate production and sales networks; sustainable farming and carbon-sequestration initiatives are further boosting demand for soil-improving fertilizers; and universities and agricultural extension services continue to promote the scientific application of ammonium sulfate—all factors driving market growth.

Mexico: Agricultural industrialization stimulates domestic demand. Mexico’s domestic crop cultivation is expanding, agricultural exports are scaling up, and modern fertilization strategies are being rapidly adopted. Leveraging its geographic and trade advantages within North America, Mexico has developed an increasingly robust agricultural supply chain, while ongoing agricultural modernization projects continue to create new growth opportunities for ammonium sulfate.

Germany: Green agriculture and stringent environmental regulations. Germany is a benchmark for sustainable agriculture in Europe, characterized by strict environmental laws and high standards for nutrient management. Cooperatives and leading chemical companies focus on developing eco-friendly, efficiency-enhancing ammonium sulfate products; they leverage local R&D capabilities to optimize formulations and export to multiple European countries, thereby driving market growth.

France: Crop diversification alongside ecological farming. France boasts a well-established, diverse cropping structure for grains, oilseeds, fruits, and vegetables, with an accelerating rollout of ecological farming projects. Agricultural cooperatives champion balanced fertilization strategies, and the cultivation of premium agricultural products drives demand for high-quality ammonium sulfate.

United Kingdom: Optimizing fertilizer usage through a focus on quality and efficiency.
